I smoked for 25 years , 1.5 packs a day. I started using e-cigs 3 months ago to cut back on the amount of cigarettes I smoked . I also was trying to save money as e-juice is cheaper then a pack of cigarettes in Canada. I ended up totally quitting when I woke up one morning and smoked the last cigarette in my pack and I haven’t gotten around to buying another one quite yet. Its been about a month I don’t suppose I will be buying another pack .I use an ego twist E-cig with an pro-tank when I am out . At home I use an evic with pro tanks. Before the e-cig I tried the patch , Nicotine gum, Chantix , counseling , Cold turkey , the lozenges , I tried another drug that was an anti depressant, Cutting back . Nothing worked at all . So far I can breath better , sleep better ( no more snoring) , I can taste and smell again. Harm reduction . That is the most important part . No matter how you look at it there is far less chemicals in e liquid then there are in a cigarette .
